Transistor DefinitionA transistor is defined as a semiconductor device used to amplify or switch electronic signals.Types of TransistorsThere are two main types of transistors: Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs).BJTsThese are current-controlled devices with three terminals (Emitter, Base, Collector) and can be further classified into various types like Heterojunction Bipolar Transistors and Darlington Transistors.FETsThese are voltage-controlled devices with
